10 Claims.

My invention relates to a shingle painting and staining mechanism and myobject is to provide a simple, inexpensive and emcient mechanism of thischaracter for automatically applying paint,

I stain, or other liquid in a uniform manner to shingles.

In carrying out my invention I employ a relatively long housing and aconveyer for conducting the shingles through said housing. Duringpassage of the shingles through the housing the paint or stain isapplied to one or both sides, as preferred, of each shingle and thensmoothed off to provide a uniform coating during which operation thesurplus paint or stain is also removed.

Adjustable means are provided for exposing more or less of the area ofthe shingles to the action of the paint or stain applying means, sothat, for instance, almost the entire area may be coated or only thatportion may be coated which is to be exposed to the weather when theshingles are applied to a roof.

Means are also provided for thoroughly mixing the ingredientsconstituting the paint or stain while the mechanism is in operationsothat the color may be uniform and all of the shingles will present thesame appearance when coated.

Means are also provided for forcing the contents of the mixer to thepaint or stain applying means and for collecting and returning thesurplus paint or stain tothe mixer for reuse.

In order that the invention may be fully. understood, reference will nowbe had to the accompanying drawings, in which:

Fig. 10 is a detail perspective view of a shield which may be employedwhen the shingles are to be given variegated colors.

Fig. 11 is a fragmentary perspective view of a portion of the conveyer.

In carrying out the invention I employ a suitable housing 2 consistingin the present instance of a skeleton frame 4 inclosed in sheet metal orother 5 suitable walls 6. The housing 2 is mounted upon casters 5 sothat it may be readily moved and its bottom portion is reinforced with abed plate 4a to carry certain mechanism hereinafter described.

8 designates a conveyer comprising a pair of endless belts Ill each ofwhich runs around a pair of pulleys l2 operably mounted upon the upperportion of thehousing 2. Thebelts l0 are arranged side by side and closetogether to frictionally en-, 15 gage and carry the shingles A from thefront to the rear of the housing 2.

The belts l0 extend substantially the full length of the housing 2 andmay be provided. with spurs [4, Fig. 11, to more reliably hold theshingles A from displacement during their progress through the housing2. One of the belts I0 is driven by suitable mechanism and drives thecompanion belt by frictional contact with the intervening shingles A.The driving mechanism consists in the present instance, of a shaft [6upon which one of the pulleys I2 is fixed, bevel gear wheels l8 and 20,pulleys 22 and 24, an endless belt 26 and a motor 28.

30 designates a guide for holding the upper edges of the shingles A inhorizontal alinement 30 while passing through the housing 2. The guide30 is adjustably supported above the housing 2 so that it may be raisedor lowered to accommodate shingles of different lengths and also act asa gage in determining how large an area of each shingle is to be exposedto the paint or stain. The guide 30 is supported by studs 32 and nuts33. The studs 32 are supported by brackets 34 secured to the top of thehousing 2 and provided with longitudinal slots 36 to permit the studs32, which project therethrough, to move up and down with the guidemember 30 when the nuts 33 are loosened. As shown by Figs. 1 and 2 theforward end of the guide 30 projects beyond the front end of the housing2 and cooperates with a short guide 38 in directing the shingles Athrough an inlet slot 40 in said front end. The guide 38, like the guide30, is adjustable up and down to accommodate shingles of differentlengths and for that purpose is secured to the housing by means of setscrews 42 which extend through a vertical slot 44 in the guide 38. Therear wall of the housing is provided with an outlet slot (not shown)similar to the inlet slot 40 and communicating with the latter through aslot 56 extending longitudinally through the top of the housing 2 forthe passage of the shingles.

The paint or stain is applied to the shingles A by suitable means suchas a pair of oppositely disposed brushes 46 between which the shinglesare adapted to pass edgewise as shown by Fig. 3. The brushes 46 areadjustably mounted so that they may be moved toward each other as thebristles 48 thereof are worn away by frictional contact with theshingles. The supporting means for each brush 46, consists, in thepresent instance of stud bolts 50 and nuts 52, which latter are threadedupon the former. The adjacent ends of the stud bolts 50 are-secured toangleirons 54 forming the upper longitudinal portion of the skeletonframe 4 and spaced apart to leave the intervening slot 56.

The brushes 46 are supplied with paint or stain from a suitable mixer 58by means of a pump 60, a feed pipe 62 leading from the lower portion ofthe mixer 58 to the pump 60, and a pipe 64 leading from the pump 60to'rlischargenozzles 66, all of which are located in. the housing 2. Thenozzles 66 extend upwardly between the bristles 48 of the brushes 46,Fig. 6, and discharge against Spreaders 68 located at the upper portionof the brushes for directing the paint or stain downwardly over thebristles 48. The nozzles .66 are flexible so that they maybe movedtowards or away from each other when the brushes 46 are adjusted uponthe stud bolts 50 and one of the nozzles 66 is provided with a valve I0for cutting off the paint or stain to the respective brush when it isdesired to coat but one side of the shingles. The pump '60 is drivenindependently of the conveyor fl by suitable means such as a motor I2,sheaves I4 and '16and .a belt '86.

The feedpipe 62 is provided with a union 82 so that it may be uncoupledfrom thepump 60 when it is desired to swing the mixer 58 outwardly fromthe housing 2, Fig. '8, preparatory to supplying said mixer with paintor stainand so that it may beconveniently cleaned when desired. Beforeuncoupling the feed pipe-62 from the pump 60, a valve connected to saidfeed-pipe 62, may be closed to retain any paint or stain present in themixer 58. In order that the mixer 58 may be readily swung outwardly orinwardly it is mounted upon hinges 86 and 88 and rails 90, which latterlead to an opening 92 in one side of the housing 2. The opening 92 isnormally closed by a door 94 to exclude dust and other foreign matterfrom the interior of the housing '2. The door 94 is connected to thehousing by a hinge 9650 that said door may be swung upwardly out of theway when opened.

The mixer 58 isequipped with a shaft 88 provided with an agitator I 00for mixing the ingredients constituting the paint or stain. The shaft-98is drivenindependently of the conveyor "8'and the pump 60 by a motorI02, gear wheels I04 and I06, a shaft I08 and gear wheels 0 and H2. Asshown the foregoing driving mechanism is mounted upon the mixer 58 toswing outwardly or inwardly therewith so that the agitator I00 may bedriven while the mixer is in either position. The gear wheel I I2 issecured to the agitator shaft 98 by means of a set screw H6 so that saidgear wheel maybelifted from said shaft when it-is desired to remove thelid II4 from the mixer-58 preparatory to filling or cleaning out thelatter.

After a coat-of paint or stain-has been applied to one or both sides ofthe shingles A by the brushes-46, it is smoothed off to approximatelyuniform thickness and the surplus-paint or stain is removed by aplurality of brushes I20 spaced a suitable distance to the rear of thebrushes 46. The brushes I20 are somewhat similar to the brushes 46,excepting that they are arranged at an angle to the shingles instead ofparallel therewith. The brushes I20 are adjustably connected to theangle irons 54 by studs I22 and nuts I24 so that said brushes may beadjusted toward each other as the bristles become worn.

The surplus paint or stain dripping from the shingles A and the brushes46 and I20 falls into troughs I 26 and I 28 which slope downwardly fromthe ends of the housing 2 to a spout I30, which :latterudischarges thesurplus paint or stain into the. mixer 58 for reuse through an openingI32 in the lid II4. The entrances to the spout I30 and the opening I32have screens I34 and I36, respectively, to catch any splinters or otherforeign matter removed from the shingles by the brushes 46 and I26. Thetroughs I26 and I28 areqnearly' as wide as the interior of the housing2. to catch the surplus paint or stain and prevent it-from-splashiingupon the mechanism located in the lower portion of the housingZ.

In eorderto enhance the appearance it is sometimes desirable to apply avariegated color to that portion of each shingle which-is to be exposedto the weather when the shingle is laid upon.:a roof. The variegatedcolor is obtained by applyingpaint of one color to the shingles with thebrushes .46 and then spraying-paint of another color ,by suitable meansnotshown, over the first coat of paint .as the shingles travel behind ashield" I38 which is suspended in the rear. part of thehousingby studbolts-l40 projecting from the adjacent angle iron 54. The shield I38prevents wastage of the sprayed paint as it is of such size asto coverall but that portion which is-exposed to the weather when the shinglesare laid upon the roof.

Briefly stated the operation is as follows: The shingles A are placedone by one between the guides30 and 38 and then pushed between the beltsI0 of the conveyor 8 which carries the shingles to the rear end of thehousing'Z. In their passage through the housing the shingles are coatedwith paint or stain suppliedeto one or both of the brushes 46, aspreferred, by. the pump 60 which draws the paint orstain from the mixer56 through the pipe62 and forces it-to one or both brushes 46 throughthe pipe 64 and the nozzles 66. Some of the surplus paint or stain dripsfrom the shingles into the trough I26 which conducts it back to themixer '58: for reuse. As the shingles pass between the brushes I 20 thepaint or stain is smoothed uniformly upon the surface of the shinglesand more of the surplus paint or stain isbrushed off .and falls into thetroughs I26 and I28 which conduct it back to the mixer 58. As the coatedshingles are discharged from the rear :end of the housing 2 by theconveyer 8, means are provided for receiving said shingles-but sincesuch means forms-no part of the present invention it was not-deemednecessary toshow or describe the same.

When the guide :30 is loweredthe shingles A are also lowered as theypass'through the housing :2, so that more of their surface is exposed tothe brushes 46, and whensaid guide is raised the shingles pass throughthe-housing on a higher plane so that less of their surface will contactthe brushes 46. 7
